task: seek record that contains a specific IP --- I have tried: 
select * from table where field regexp '^10.100.1.1'
select * from table where field regexp '10\.100\.1\.1'
select * from table where field regexp '10\.100\.1\.1[[:>:]]'
select * from table where field regexp '[[:<:]]10\.100\.1\.1[[:>:]]'

and so on . . . all same result - many matches where even the first six character do not match - help! 
mysql> select d07 from service where d07 regexp '^10.100.1.1';

here is the behavior I expected: mysql> select d07 from service where d07 regexp '10.100.101.95'; +-----------------------------------------+ | d07 | +-----------------------------------------+ | 10.100.101.95 on at 2011-05-24 02:08:49 | | 10.100.101.95 on at 2010-04-24 15:00:04 | +-----------------------------------------+ 2 rows in set (0.05 sec) could it be that there is something magic about 10.100.1.1?
